Patent GB-827831-A (GB)
Title: Improvements in or relating to amines
Inventor: LEE GLYNN EVAN
Filed: 1956-05-22
Abstract: The invention comprises compounds of the formula <FORM:0827831/IV (b)/1> (wherein X and Y each represent a hydrogen atom or together represent a bond and R1 and R2 each represent an alkyl group of at most 6 carbon atoms), including their geometrical and optical isomers and mixtures and racemates thereof, and acid-addition salts thereof; and their preparationf by reduction of compounds of the formula <FORM:0827831/IV (b)/2> by methods known for the reduction of a nitro group to an amino group with or without concomitant reduction of an ethylenic double bond.  When both groups are to be reduced the reductions may be effected simultaneously or separately.  Preferably, catalytic hydrogenation with Raney nickel is used for simultaneous reduction and iron and hydrochloric acid in a solvent medium for reduction of the nitro group alone.  Examples are given, in which R1 and R2 are each methyl.  Compounds of the formula II are prepared by Diels Alder condensation of cyclopentadiene and the appropriate nitro-alkene. Specification 827,832 is referred to.

Title: Improvements in and relating to valves adapted for use in hydraulic power transmission systems
IPC: F15B13/00
Filed: 1940-10-30
Abstract: 548,175. Valves. NASH, A. G. FRAZER-. Oct. 30, 1940, No. 15873. [Class 135] A hydraulic control valve particularly adapted for use in a gun turret for controlling the power cylinders for imparting motion of elevation and depression to the guns and for securing azimuthal motion thereof has the several valve members slidably mounted in a common housing which is provided with supply and exhaust connections leading to the power cylinders and to a power supply. In the form shown in the Figure the housing accommodates three separately actuated piston valves, 43, 47, 49, slidably mounted in ported liners 23, 24, 25 secured by screwed plugs 26 and distance pieces 29 in three parallel cylindrical bores 2, 3, 4 in the common casing. The valves 43, 47 control the power cylinders while the valve 49 is adapted either to connect the supply conduit 20 directly to the return main 21a by way of ports 42, 42a or to connect conduit 20 to a series of annular grooves 12, 12a, 12b, surrounding the lines and connected by passages 13 and the exhaust conduit 21a to two similar series of annular chambers 5, 5a and 11, 11a, 11b connected by passages 6, 8 and 10. The valves 43, 47 are normally held in a central neutral position by springs 46, 46a acting on abutments 45, 45a adapted to co-operate with shoulders in the liners. The valve 49 is normally held in the short circuiting position by a spring 51. Annular grooves 14, 14a and 16, 16a surrounding the liners are connected to the power cylinders. Movement downward of the valve 43 connects the supply passage 13 to the annular groove 14a by way of ports 33, 34a and at the same time the annular groove 14 is connected to the return main by way of ports 31, 34 and passages 5, 8, 10 and 11. An upward movement reverses these connections. The valve 47 operates in a similar manner.

Title: Improvements in high voltage electrical switching devices
IPC: H01H33/14
Filed: 1947-06-17
Abstract: 632,718. Gas-blast switches ; arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd., and ROXBURGH, A. June 17, 1947, No. 15959. [Class 38 (v)] Resistors 6 comprising a truly ohmic portion 7 and a non-linear portion 8 in series, are connected in parallel across the contacts 1, 2 of a multi-break circuit-breaker. The value of the non-linear portions 8 is sufficiently high to permit breaking of the final resistance current, at normal recovery voltage, on a plain air-break switch 5, the value of the linear portions 7 under this condition being relatively negligible. Also, the value of the non- linear portions 8, when subjected to high voltage, is such as to damp the high voltage restriking transient. Should one break 1, 2 restrike, the high voltage is imposed across the remaining resistors 6 not associated with that break, and in the absence of the linear portions 7a dangerously high current would flow through those resistors, but by providing the linear portions 7, this current is limited and also the remaining breaks 1, 2 are caused to restrike.

The speed of a D.C. motor driving a lathe is controlled so that the peripheral speed of a work-piece in the lathe is maintained constant. The output of a tachometer 4 coupled to the motor 1 is applied to a linear potentiometer 5 from the stator of which is obtained a control voltage which is compared with a reference voltage 74 to control an amplifier 71 which in turn controls the rectifiers 32, 33 supplying the motor armature. The position of the slider is dependent upon the radial position of the tool post 6 of the lathe with respect to the axis of the work. Hence the motor speed is increased as the tool advances, thereby maintaining a constant peripheral cutting speed.
